You can import Endless Aisle app settings using EA_preferences.zip file, but first you must change the directory name to the name of your site. However, you can only import the EA_preferences.zip file that is included with the Endless Aisle app if SiteGenesis is your site name. Otherwise, follow steps 4-6 to recreate the .zip file.
Any preferences specified in preferences.xml will overwrite any Endless Aisle app settings currently specified in Business Manager. If you want to keep existing Endless Aisle preferences, export them, merge the preferences.xml files, and then import them.
